SUMMARY -- Effective teamworking is one of the main skills currently
demanded by employers. Consequently, several
learning methodologies have been including group activities
in last years. Nevertheless, it is not clear how
a piece of work made in group should be assessed and
graded. This article describes the evolution, through 3
academic years, of our technique for grading the projects,
made in teams, of a Software Engineering subject.
For each described solution, strengths and weaknesses
are analysed and lessons learned are commented.
